Waste Management Controlled Demolition
Waste Management, Inc. (Owner), The BG Group (BG – Demolition Contractor), and Controlled Demolition, Inc. (CDI – Implosion Subcontractor) of Phoenix, Maryland, would like you to be aware that on Friday, the 7th of June 2024, as soon after 10:00 AM, as safety and preparations permit, the Wheelabrator Refuse Plant Boiler House and 199’ Chimney will be demolished by implosion to an elevation where BG can safely access the debris for secondary demolition and processing.
Implosion is a process where a small amount of explosives is used to disrupt selected supports in a structure. This allows gravity to pull the structure down in a controlled manner. CDI has used this implosion method thousands of times around the world during the past 65 years to assist Property Owners and Contractors in the removal of unwanted structures.
There are four (4) points we would like to make you aware of:
1. Dust is an unpreventable byproduct of all types of demolition. With a wrecking ball or high-reach excavator, the structure is slowly broken up, releasing dust over a lengthy period of time. With implosion, the same overall quantity of dust is released in a matter of seconds and may linger in the general area for 4 to 6 minutes before BG crews begin cleaning the same area from the streets and sidewalks. Depending on wind speed and direction on the day of the implosion, the dust may or may not reach your properties. As a precautionary measure, we recommend that you see that all windows, doors, and air intakes are closed and cover any other openings that might allow dust to enter your apartment, house, or building. We also recommend that you turn off all exhaust fans before or at the time of the implosion, as these might draw air into your building through cracks in walls and windows.
2. Early Friday morning, the Broward County Sheriff’s Department will set up an Exclusion Zone around the structures. This is to prevent people from getting too close. Your property is INSIDE this Exclusion Zone and related traffic and pedestrian detours. The detours should go into effect approximately 30 minutes before the implosion and last until about 30 minutes after it. We ask that you plan for no traffic in and out of your site during that time. We need your cooperation with the Police and contractors to ensure this is a safe job. Everything they say to you or ask of you is to minimize inconvenience or to promote safety.
3. There will be heavy dust in the block immediately surrounding the demolition site. Dust may also drift outside and downwind of the Exclusion Zone, depending on weather conditions. Please stay indoors during the demolition.
4. More than 100 years of vibration/noise monitoring data assembled by the US Bureau of Mines established guidelines for safe vibration and noise levels around blasting sites.
For several days prior to the implosion, a pre-demolition photographic survey will be conducted to document the pre-existing condition of adjacent structures and properties in accordance with state law. Noise and vibration monitoring instruments will be set up around the demolition site to monitor actual levels of noise generated by the implosion/fall of the Wheelabrator structures.
A follow-up post-implosion survey will be conducted on the morning of the implosion to determine whether or not any changes have taken place in the structures previously inspected. The vibration and pre/post-survey reports go to the State of Florida to protect the interests of all parties involved.
